ARCHIVE #87B
BACKSTORY
CASE FILE: MASON R.
In 1990, a sixteen-year-old boy named Mason R. began exhibiting increasingly violent behavior. Psychiatrists recorded disturbing interviews, interpreting classic indicators of young psychopathic tendencies. Mason disappeared on Halloween night in 1990, his parents finding only a room emptied of all sharp objects, and a discarded, decades-old Spider-Man costume left behind.
Investigators found troubling archived recordings years later. Sightings matching Mason's description continue to surface.

SUBJECT PROFILE
SUMMARY OF BEHAVIORAL CONCERNS
Mason exhibited psychopathic and antisocial traits from early childhood. Referred for psychiatric evaluation at age 16. Over 78 recorded sessions in 1990, clinical staff documented a persistent pattern of emotional detachment, manipulative behavior, and an unsettling fixation on predatory observation.
Key behavioral indicators:
— Emotional flatness; described as "performing" feelings
— Minimal blinking; initial refusal to speak in sessions
— Reactionless observation of dead house cat shown by mother
— Standing motionless at night in the dark
— Fascination with collecting and hiding sharp objects
— Incident with neighbor's dog — [SEALED]
"It was like he was repeating us, rather than feeling anything of his own."
Disappearance — October 31, 1990:
Mason's room was found emptied of all sharp objects. A yellow 1950s-era Spider-Man Halloween costume — plastic smock-type — was left on the bed. The costume had not been purchased by the family. Its origin remains undetermined — see Exhibit A.
